Code P0111 Mitsubishi Description
The P0111 diagnostic trouble code (DTC) for Mitsubishi vehicles indicates an issue with the Intake Air Temperature (IAT) sensor circuit, specifically a range/performance problem. The IAT sensor is responsible for measuring the temperature of the air entering the engine, which is crucial for the proper functioning of the engine control system. When the IAT sensor provides inaccurate or out-of-range readings, it can lead to various performance issues in the vehicle.
Common Causes of P0111 Mitsubishi
- Faulty IAT sensor
- Damaged wiring or connectors in the sensor circuit
- Corrosion or contamination in the sensor connector
- ECM software issues
- Intake air leaks near the sensor
Symptoms of P0111 Mitsubishi
- Check Engine Light illuminated on the dashboard
- Decreased fuel efficiency
- Rough idling or stalling
- Engine misfires
- Lack of power or poor acceleration
How to Fix P0111 Mitsubishi
- Begin by visually inspecting the IAT sensor and its wiring for any visible damage or corrosion.
- Test the IAT sensor using a multimeter to check for proper resistance values within the specified range.
- Check the sensor circuit for continuity and repair any damaged wiring or connectors as needed.
- Clear the DTC with a scan tool and test drive the vehicle to ensure the code does not return.
- If the issue persists, consider replacing the IAT sensor or consulting a professional for further diagnosis.
Cost to Fix P0111 Mitsubishi
The typical repair costs for addressing a P0111 code in a Mitsubishi vehicle can range from $100 to $300, depending on the specific cause of the issue and the cost of parts and labor.

Frequently Asked Questions about P0111 Mitsubishi Code
1. What does the OBDII code P0111 mean on a Mitsubishi?
P0111 indicates an "Intake Air Temperature (IAT) Circuit Range/Performance Problem," meaning the IAT sensor is reporting erratic or out-of-range temperature readings to the engine control module (ECM).
2. What are common symptoms of the P0111 code in a Mitsubishi?
Symptoms may include poor engine performance, reduced fuel efficiency, rough idling, difficulty starting, and the check engine light turning on.
3. What causes the P0111 code on a Mitsubishi vehicle?
Common causes include a faulty IAT sensor, damaged sensor wiring, loose or corroded electrical connections, or issues with the ECM.
4. Can a dirty air filter cause the P0111 code in a Mitsubishi?
While not a direct cause, a clogged or dirty air filter can affect airflow and indirectly contribute to inaccurate readings from the IAT sensor.
5. How do you diagnose the P0111 code on a Mitsubishi?
Diagnosis involves scanning for codes, visually inspecting the IAT sensor and wiring, testing the sensor with a multimeter, and checking for proper voltage and resistance.
6. How do you fix the P0111 code on a Mitsubishi?
Repairs may include replacing the IAT sensor, repairing or replacing damaged wiring or connectors, cleaning the sensor, or reprogramming the ECM if needed.
7. Can I drive my Mitsubishi with the P0111 code?
Driving with the P0111 code is possible but not recommended, as it may lead to reduced performance, poor fuel economy, and potential long-term engine damage.
8. Where is the Intake Air Temperature (IAT) sensor located in a Mitsubishi?
The IAT sensor is usually located near the air intake system, typically within the air filter housing or attached to the intake manifold.
9. How much does it cost to fix the P0111 code on a Mitsubishi?
Repair costs can range from $50 to $300, depending on whether the IAT sensor replacement or wiring repairs are needed.
10. Can a P0111 code clear itself on a Mitsubishi?
In rare cases, the code may clear itself if the issue is intermittent, but it’s typically necessary to repair the underlying problem and reset the code with an OBDII scanner.
